You can put this solution on YOUR website!
The unstated imaginary zero of -2i is also necessary.
The function is f%28x%29=%28x-1%29%28x-2i%29%28x%2B2i%29, which you might want to write without directly showing imaginary components, so you could multiply the two non-real binomial factors:

x%5E2-4i%5E2
x%5E2-4%28-1%29
x%5E2%2B4
-
Your function is then f%28x%29=%28x-1%29%28x%5E2%2B4%29
